Waaay back when there was a store called "The Wiz" and the log was "Nobody beats the Wiz". The store near me had the logo on the windows and someone had scratched out all the Bs. So now it said "Nobody eats the Wiz"

There's a Ford dealership near St. Augustine, FL called Bozard Ford. The first time I saw a car with their tag, I thought it read Biohazard. Somehow I think a dealership called Biohazard would have much more interesting vehicles than your plain vanilla Ford dealership.

This is actually mishearing instead of misreading but maybe it counts. A shampoo commercial was on earlier. It said, "Try pure renewal." I heard it as "Try pure manure." For a moment I thought gross! Manure on your hair?

Saw a cool upscale grocery store with the name "Gourmet Garbage." Only when I told my friend that I really wanted to check out "Gourmet Garbage," she looked very confused, then burst out laughing. It was "Gourmet Garage."

When I was in college, some student protesters had spraypainted "FREE MUMIA!" several places around campus. I was walking with my roommate when I first saw it and commented "What is mumia, and who's giving it away free?"
